Sacral Parasympathetic Nucleus
@@Home -> BiologicalLifeResearch -> BrainAreaLAC -> BrainRegionLAC_SC_IZ_SPS
This page covers biological details of component Sacral Parasympathetic Nucleus. Region is part of aHuman target integrated biological model.
- Top-down path to region: Spinal Cord -> Intermediate Zone (SC.IZ) -> Lamina VII (SC.IZ.L7) -> Intermediolateral Column (AVA.SC.IZ.IMLC) -> Sacral Parasympathetic Nucleus (LAC.SC.IZ.SPS) (see Mind Maps)
- Type: nucleus
- Quality: L0
- Brain area: Lower Brain - Autonomous Control Area (LAC)
- Area circuit: Sacral Autonomic Control (LAX)
- Role: parasympathetic.nucleus
- Function: parasympathetic impulses pass via postganglionic fibers to the urinary bladder, erectile tissues, and the smooth muscles and glands in the colon and rectum
- Notes to function:
- from Lamina VII, visceral parasympathetic
